Microsoft let slip that with the launch of Windows Server 2012 R2, it will release its Remote Desktop app not just on Windows, Windows RT and OS X, but also iOS and Android later this month



From Engadget:

This marks the first time the popular remote desktop software has made it to the rival mobile platforms, and could prove to be a shot across the bow to other apps in the same space. Michel Roth, one of Microsoft's Most Valuable Professionals, adds that the OS X app has undergone a major overhaul, the iOS version will support iOS 6 and 7, while the Android variant should support everything from Gingerbread upward.
